Intel has confirmed that it won't be allowing 11th Gen Rocket Lake Desktop CPU compatibility on existing B460 & H410 chipset based motherboards. According to Intel, the CPUs will officially get support on Z490 & H470 motherboards while the more budget-oriented offerings will be left out.

On its official support page, Intel states that motherboards based on the Intel B460 & the H410 chipsets are not compatible with Intel's 11th Gen Desktop CPUs. Now Intel 11th Gen CPUs come with both Rocket Lake and Comet Lake Refresh flavors. The entry-level 400-series motherboards will retail support for 11th Gen Comet Lake Refresh CPUs which will include Celeron, Pentium, and Core i3 parts but won't be receiving support for the Rocket Lake lineup which includes Core i5, the Core i7, and Core i9 SKUs.
